摘要： An optical hinge (20) provides one or more free space optical communication links through the hinge (17) of an instrument (10). The optical links include a transmitter (24) in one section (14) of the instrument (10) and a receiver (34) in the other section (16) of the instrument (10). An optical coupler (27) connects the transmitter (24) to the receiver (34) through a hinge (17).

摘要： A teleconference system including a plurality of personal presence cells positioned at a local communication site and at a remote communication site. The plurality of personal presence cells are characterized as either sensor cells or display cells. The sensor cells include at least one video camera positioned to sense and transmit an image of the local participant, and an image screen positioned to reflect an image of the local participant toward the at least one video camera and for viewing of an image through the screen. The display cells each include at least one projection display positioned to display a multi-dimensional image of a remote participant on a display screen. A transmission link interfaces the plurality of personal presence cells positioned at the local communication site and the plurality of presence cells positioned at the remote communication site.
